POLYBUTYL-OR POLYISOBUZYLAMINES,HYDRAZINES OR HYDRAZIDES, METHOD FOR PREPARING SAME AND USE AS DETERGENTS IN FUELS

摘要

The invention concerns polybutyl-or polyisobutylamines-hydrazines or hydrazides, a method for obtaining them which consists in subjecting to hydrohalogenation a polybutene or polyisobutene in the presence of oxygen and in aminating the resulting brominated compound or subjecting it to a reaction with hydrazine or still with an alkaline metal azide. The invention also concerns their use as detergents in fuels.
